To aZZw/wm it may concern:

Be it known that I, EDWARD E. R IoH, a citizen of the United States, anflmgt resident of the city of Chicago, county of Cook, and State ofIllinois, have inventedfcertain new and useful Improvements in LockingDevices for Pressing Machines, of which the mechanism, showing thedevice in locked pofollowing is a specification.

My invention relates to a, locking device, and more particularly to alocking device for a pressing machine, and has for its eb-- ject theprovision of means which willlock down the upper pressing member ofsucha machine upon the garment on the lower pressing member.

Another object-is the provision of locking means for the operatingtrea'dle of amachine.

Other objects will appearyhereinafter.

The invention consists in the combinations and arrangements of partshereinafter .de-' scribed-and claimed.

" The invention will be best understood l iy reference to theaccompanying:drawings forming'a part of this specification, and inwhich, 1 I i 1 is side view ofa' pressing machine with myinventionapplied thereto,.the locking device being shown in releasedposi-"- tion.' N 5 Fig. 2'is' a" detailedview of the locking sition. v

The drawings illustrate a table 6 supported upon legs 7, which areconnectedby brace .bars 8. Brackets 9- are mounted on. the table and astationary pressing member or board 10 is fastened on said brackets,extending lengthwise of the table. A bracket 11, provided withsleeves--12, is fastened to the rear edge of said table, and a' shaft 13is mounted for vertical movement in said sleeves. A supporting bar 1 1is adjustably mounted on the upper end of said shaft, as by means of aset screw 15, or in any convenient manner, and an arm 16 is pivoted withone end upon said bar, as at 17 ,and its free end is attached to andsupports a pressing member or iron 18, adapted to co-operate with thepressing board 10 beneath the iron, to press garments and the like, asis well understoood. i

A rod 20,is pivoted with one end upon a pin 21, in a bracket 22 fastenedbeneath the table, and with the other end pivotally engages the lowerend of the shaft 13. A collar 23 is mounted upon the intermediate lower.end, which is connected with one end to" treadle lever- 25,

While I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification without departing from the spirit of theinvention. I, therefore, do not wish to be limited to the'precisedetails of construction set forth,

but desire to avail myself of such variations and modifications as comewithinthe scope of the appended claims.
